Pros
Great starting salary compared to the average on the Portuguese market (which they exploit later on), some benefits, like life insurance and and private health insurance, good initial training, nice ambiance, the team I worked with was exceptionally great.
Cons
As soon as they see the potential in you, they will add more and more to your workload and responsibilities without increasing your salary. Extra hours are not paid but expected. Communication between departments is difficult. A promotion is rare and does not come with much of a raise. There is no transparency in the decision-making process, however some people are "more equal" than the others. The most disturbing is that the French way of management is just a propaganda to accept things as they are because "it could be much worse". After a while there is no room for personal development, the company just exploits you and churns the life out of you. They do not appreciate their human capital enough, they just want the cheaper multilingual workforce in Portugal because most employees are monolingual in France. The KPIs for the bonuses are unattainable, unrealistic and unfair.
